Title: Fixing device of electrophotographic copying machine
Inventor: ISHIDATE YOSHIYUKI
IPC: H05B3/00
Filed: 1982-05-13
Abstract: PURPOSE:To ensure uniform fixing by providing a pressing roll with a heater in the inside. CONSTITUTION:A coat layer 9 made of rubber or the like rich in heat resistance and elasticity is applied onto the outer circumference of a hollow cylindrical core metal 8 to form the pressing roll 7, and IR lamps 10 are arranged in the center of the core metal 8 to serve as a linear heater. As the roll 7 has been preliminarily heated with the lamps 10 when a heating roll 1 contacts with the roll 7, an amt. of heat transferred from the roll 1 to the roll 7 is small, the surface temp. distribution of the roll 1 exerting large effect on the result of fixing is maintained almost uniform, and hence, uniform copying is attained throughout the whole width of a copying sheet. Although continuous copying is executed, the roll 1 is not cooled remarkably on account of a small amt. of heat transferred from the roll 1 to the roll 7, and so, fixing performance is maintained uniform.

Title: Electromagnetic hammer with support moving mechanism
Inventor: KOGA YOSHIO
IPC: B22D11/128
Filed: 1995-04-04
Abstract: PURPOSE: To make a reception of a impact reaction force of a floating support type electromagnetic hammer(EMH) sufficient and to improve the efficiency of striking and drawing by connecting the EMH to a base frame through an EMH support moving mechanism. CONSTITUTION: Because an EMH 7 is connected to a supporting base 3 of a base frame 2 through a hydraulic mechanism 13, in a case of striking a cotter 6 with the EMH 7, by operating the EMH mechanism matching to the action of this EMH 7, the impact reaction force generated in a moment of striking the cotter 6 can be received with this hydraulic mechanism 13, the impact force of the EMH 7 is cancelled with the impact reaction force and the efficiency of striking can be prevented from being cancelled. Further, drawing and moving of the cotter 6 can be drawn out and moved by this hydraulic mechanism 13, and the EMH 7 is moved easily to the striking position.

Title: Semiconductor laser driving device
Inventor: SATO KOJI
IPC: G03G15/04
Filed: 1986-04-08
Abstract: PURPOSE:To emit laser light having an excellent extinction ratio by providing current control means for correcting a threshold bias current value by a predetermined amount to apply it to a semiconductor laser, and applying a bias current near the threshold value to the laser to improve frequency and thermal characteristics. CONSTITUTION:When a controller 5 which is used also as correcting means calculates nonlight emitting bias current value IBIAS, it feeds the bias current value IBIAS to a latch 7, and applies the value IBIAS to a semiconductor laser 1. The controller 5 feeds data for increasing a light emitting current to a latch 8 until a predetermined quantity of emitted light is obtained. In other words, the current of a light emitting constant current circuit 4 added to the bias current of a bias constant-current circuit 2 is applied to the laser 1. When the laser 1 emits a predetermined light quantity by the added current, the controller 5 stops transferring data, holds the value at the latch 8 and instructs a laser OFF signal to a switching circuit 3.

Title: Generation method of linear prediction coefficient signal
Inventor: PIITAA KURUUN
IPC: G10L19/04
Filed: 1995-03-13
Abstract: PURPOSE: To expand the band width of peak in frequency response by generating a linear prediction coefficient signal during frame erasure based on the weighted interpolation of a linear prediction coefficient signal generated during a non- erased frame period. CONSTITUTION: The linear prediction coefficient signal generated during the non-erased frame period is stored in a buffer memory. When frame erasure occurs, the set of final 'satisfactory' coefficient signals is weighted by the accumulation of band expansion coefficient. The index of accumulation designates the coefficient. In response to the frame erasure, the stored linear prediction coefficient signal is corrected so as to expand the band width of peaks more than one in the frequency response of linear prediction filter, and the corrected linear prediction coefficient signal is sent to the linear prediction filter so as to be used in the case of synthesizing an audio signal. Thus, the degradation of sound quality caused by frame erasure in a communication system, for which audio encoding is utilized, is reduced.

IPC: G06F15/78
Filed: 1986-04-07
Abstract: PURPOSE:To ensure the effective application of a pipeline by deciding the number of stages of a control register according to an optimum number of stages obtained from the number of cycles counted in a period between a time point when the pipeline is started and the write mode of a vector register and the optimum number of stages and the access timing cycle of a bank of the vector register. CONSTITUTION:A period covering the starting point of an access pipeline 1 and/or an arithmetic pipeline 3 through the writing time point of a vector register 2 is referred to as N together with the access timing cycle of the register 2 as T respectively. Under such conditions, the number of stages of a control register 4 and/or 5 which controls the state of the instruction in the pipeline 1 and/or 3 is set at P as shown in an equation. The number of stages of the register 4 is obtained from the number of cycles counted in a period between the starting time point of the pipeline and the access timing cycle of the bank of the register 2. Thus it is possible to form a pipeline with an instruction control register having the minimum number of stages, i.e., the optimum number of stages to attain the effective application of pipelines.

Abstract: PURPOSE:To enable elimination of the need to mount a suction valve, by a method wherein a suction passage, intercommunicating the interior of a cylinder part and a cam plate chamber when a piston is situated at position near a bottom dead point, is formed in a housing, and only a delivery chamber is formed outside the housing. CONSTITUTION:A suction passage 411 is formed in a position in the vicinity of the bottom dead point of a piston 124 in a compression chamber 213, and the suction passage 411 is formed with plural suction passage holes 414 and a suction groove 413. The plural suction passage holes 414 are formed around a cylinder 123 within a housing 114, the one end thereof is open to a cam shaft chamber 225, and the other end is communicated with the suction groove 413. Thus, the cam plate chamber 225 is communicated with the compression chamber 213 through the suction passage hole 414 and the suction groove 413. As noted above, since the cam shaft chamber 225 and a cylinder 123 are communicated to a compression chamber 213 only through the suction passage 411 formed in the housing 114, a suction valve can be eliminated. Further, only a delivery chamber 214 may be formed outside the housing 114, and thus, a seal between the suction chamber and the delivery chamber can be sharply facilitated.
